Let's face it, for better or for worse, a lot of our London summer revolves around drinking. The sun comes out and a cheeky glass of Pimms, Prosecco or G&T is exactly what we're craving. But these sunny days are a rarity, and they deserve to be treated with the upmost respect. Don't offend them by spending the day inside a dingy pub, get to a rooftop bar and wet your whistle while taking in the view. Check out Stylist's (extensive) list of whose roof to be at this summer.x
